Justashooter covered it on how much coverage at different distances.
However, when you turn up the brightness, it can start to glare, and that will make appear larger, and since you cannot see through the glare, if effectively is larger.
You want the minimum brightness you can get away with.
The more expensive models will often have a cleaner, more accurately sized dot. The Bushnell and the vortex, and primary arms are probably going to be the minimums here.
Dovetail on a 30-30? Haven't heard of a red dot mount for any of the micros to fit. Also haven't heard of any 30mm dovetail rings, but I've not looked for them either.
You might have to do the rail adapter mentioned. It might get you your height without a riser.
Do you have any vision problems, like astigmatism? I spent a couple decades filling drawers with red dot because they are all very starry, and unable to use for anything requiring accuracy. Cheap Chinese, Bushnell, vortex, aimpoint, all of them. The new trijicon mro was the best, but still a bit fuzzy. However, all fiber optic powered sights are perfectly sharp.
So, if you can, look through some before buying.

Brownells carries a somewhat heavy duty Picatinn rails that attaches straight to a 3/8 inch dovetail. Has lots of tightening screws, and a vertical clamp down screw, so it should be pretty strong if both epoxied and screwed down to the receiver. (They also carry one that is a clamp down Weaver rail.) People are using these to mount scopes and optics to Mosin Nagants, which are really hard kickers, so they should be OK for a .30-30.


Yes I have an astigmatism in my right eye. Glad you brought that up.


Does this mean a fiber-optic powered unit would be better? What the heck is a fiber-optic powered unit, and how do I tell it from the other types please?

You need a prismatic sight. You have to be able to focus the reticle for your astigmatism. You should look at the vortex spitfire line of optics. Burris also makes a line of prismatic red dots.

I'm going to put a clamp-on Weaver WGRS receiver sight on it, and use locktite and JB Weld to make sure it doesn't budge (slide) in the grooves from recoil of the .30-30. I'm also going to put a Skinner XS front blade sight on it, with the white strip. I just want a good little 75 yard deer gun.
